MARC 21 Update No. 11: Full and Concise available online

Network Development and MARC Standards Office
Library of Congress

Update No. 11 (February 2010) is now available on the MARC website (www.loc.gov/marc/). It is integrated into the documentation for each of the Online Full and Concise formats that are maintained on that site -- the Bibliographic format, Authority format, Holdings format, Classification format, and Community Information format. The documentation includes changes made to the MARC 21 formats resulting from proposals which were considered by the ALA ALCTS/LITA/RUSA Machine-Readable Bibliographic Information Committee (MARBI), the Canadian Committee on MARC (CCM) and the BIC Bibliographic Standards Group in January 2010. Many of the changes in this update have been made to accommodate the new cataloging rules, Resource Description and Access (RDA). Note that no changes are needed to the Holdings, Classification, and Community Information Formats in this update.

The changes are indicated in red in Update 11. Update 10 (October 2009) changes have also been kept in red since that update was only recently issued and 10 and 11 are being combined. Each format also has an appendix, "Format Changes for Update No. 10 (October 2009) and Update No. 11 (February 2010)" that lists the changes that comprise the combined update. The Web version of the formats is the official version and is considered the start for implementation planning for MARC 21. Users are not expected to begin using the new features in the format until 60 days from the date of this announcement: May 5, 2010. For more information about format documentation see: http://www.loc.gov/marc/status.html.

The printed version of the update will be available through the Cataloging Distribution Service in the future. The print format update will combine Updates 10 and 11 into one update dated 2009/February 2010. The printed publications will be announced when they are ready for distribution.
